Fejlnumre

Fejlnumre is a term used in Scandinavian computing and technical documentation to denote numerical codes that identify error or fault conditions in software, hardware, processes, and services. They function as compact identifiers that accompany error messages, log entries, and diagnostic reports, enabling both automated handling and human troubleshooting.

The word is formed from the Danish word fejl (error) and nummer (number), and the plural fejlnumre is used to refer to multiple such codes. In practice, fejlnumre may be standardized within an organization or defined per product line, and they may be defined in technical manuals, API specifications, and error-handling policies.

Usage and format: They are commonly integers used in logs and user messages to identify the root cause of a failure. In many systems, such codes are paired with a human-readable description and a severity level, and they may be mapped to formal error types or categories for automated processing.

Examples: fejlnumre 1001 indicates an invalid_parameter, 1020 indicates a missing_required_field, and 2500 signals authentication_failed.

There is no universal standard for fejlnumre; organizations commonly design their own schemes, though some align with broader conventions such as product- or vendor-specific catalogs, or with cross-domain conventions like HTTP status codes.
